BUILDING INSULATION AND METHOD OF APPLYING SAME Application filed July 30, 1928, Serial No. 296,207. Renewed January 3%,1933.

The invention relates to an 4 improved building insulation and method of applying the same and has for its primary object the provision of an improved construction and method of this character adapted and arranged to provide economical insulation for building which is highly efficient use.

Another object of the invention is to provide an insulation for buildings especially adapted for use in conjunction with pitched or flat roofs which is capable ofeconomical application to such roofs and highly eflicient in'use. p r I Another object of the invention is the provisionof an improved method for applying such insulation to buildings. p

Other obj ects' will appear hereinafter.

The {invention consists in-the combinations and arrangements of parts and the method of application hereinafter described and claimed. H r I The invention will be best understood by reference to the accompanying. drawings forming a part of this specification and in w i 1- H V Fig. 1 isa perspective view illustrating a roof in course of construction and provided with insulation embodying the invention;

Fig. 2, a perspective view of a reinforcing .bar employed in the construction; i

Fig. 4, a top plan v1ew shown partially 35 in section, of a portion-of .the roof illustrated .inFig. 1; p h I Fig. 5, atransverse section taken substantially onfliner5 5 of Fig. 4-; V p i Fig. 6,,a transverse section taken substantially on linen-6 of Fig. 4;

- Fig. 7 ,a longitudinal section stantially online 7-7 of Fig. i; Fig. ,8, a view similar to Fig. 7

taken subbut showing the insulating blocks in final positions; and q V i Fig. 9,a detail view illustratinga slightly modified'fo'rrnof Construction. H

The preferredform of construction and method 30f applying the same comprises a frame consis ing of two endbars 10 preferablylof angI irQn and connec ed ge he by longitudinal bars 11 which are preferably H li -bars as shown. The end bars 10 are provided 1n the ends of the vertical legs thereof with notches 12 and 13 thereby forming projecting supporting lugs l land 15 adapted I and arranged to rest on the lower flange 16 of the I-beams 17 constituting the ordinary purlins of a roof construction. 1 I

The notch 12 is substantially twice the length as the notch 13, thereby forming the supporting lugs 14 substantially twice, the length of the supporting lug 15, asshojwn. This arrangement is provided soasv to per mit of the ready removal of the supporting frame from between the purlinsll? after the insulating blocks have been applied thereto... c

In use, the inner edge of the notch 13 is kept in contact with the corresponding flange 16, thereby withdrawing the" inner end of the opposite notch :12 from contact with its correspondingflange 16 as shown in Figs. land5. When it is desired to remove the-supporting frame frombetween the purlins, all that is necessary isto shift the ,frame overtoward theside of the lugs ltuntil the lugs 15 dis engage from the corresponding flange 16 whereupon the frame canbe removed from below the purlins. This permits .of theremoval of the frame after the insulating blocks :have been placed in position, said ins sulating blocks preventing removal of the frame upwardly between the purlins.

I also provide a supply'of reinforcing bars or strips 18, preferably of brass,.or other noncorrosive metal or mater al, for nsertion between the nsulatlng blocks. These rein:

forcing bars are provided withapluralityof q'ert en o indicated in Fig. '1, with thelugs 1 1i and 15 resting on the flanges .16, as shown Then w c t i a n block z nd- 212 l are placed in positionfon the sup porting frame If a een gg he and between l the purlin's.

joints 23 between the ends ofthe blocks may tion crookedly, as indicated by the dotted 'sealedjoint perfected. I p

As, each joint between two sets of blocks is be sealed by waterproof cement applied before insert-ion of the blocks. Then one of the reinforcing bars 18 is placed adjacent the edges of the blocks 21 and 22 and dowel pins 20 forced by the hand through the openings 19 and partially into said blocks, as indicated in Fig. 7. After partial insertion of the dowel pins, the reinforcing bar '18 j is withdrawn from contact with the blocks, thereby straightening up the dowels should any of them have been placed in posithus completed, the supporting frame 1011 is moved outwardly along the flanges 16 to constitute a support for the next set of blocks as shown'in Fig. l. A new reinforc- I 7 ing bar 18 is then applied as before and a new joint made. Thus the process is continued until the entire space betweenthat pair of purlins is closed by the insulating blocks, after which the supporting frame may be removed from below as explained above.

The space between each adjacent pair of purlins is'similarly filled or sealed bythe insulating blocks and then hereof covering 24: is appliedin the usual wayover the purlins l7,'thus completing the roof construction. In this way the insulation may b quickly and economically applied and a strong and durable construction provided.

7 The reinforcing bars 18 are themselves reinforced by the stiffening effect of the insulating blockson opposite sides thereof so that bars of relatively thin noncorrosive metal may be employed to hold the insulating; blocks in place. i 1' It will also be noted that the bars 18 are concealed between the insulating blocks and asmooth and attractive appearance thereby presented. V i

' The specific form and arrangement of parts disclosed is asimple and effective one for the purpose.-

In Fig. 3 of the drawings I have illustrated a 'modifiedform' of reinforcing bar 18 in which sharpened tangs 25are struck up from the bar'and extended therefrom alternately in opposite directions, said sharpened tangs obviously serving the'function of the dowel pins 20.

In the modified form of construction illustrated in Fig. 9, the steel purlins 17 are shown as covered by a concrete covering 26' having channels 27 in the opposite sides thereof. Here the process of application of the serving heat in winter ."and excluding heat in summer, and also producingthe usual acoustic efi'ects.

' While I have illustrated and described the.

preferred form of construction and method of procedure for carryingmy invention into effect, this is capable of variation and mod ification without departing from the spirit of the invention. I, therefore, do not wish to be limited tothe precise details set forth but desire to avail myself of such variations and modifications as fall within the scope of the appended claims. 1'

I claim: r

1. The method of applying building insulation-which consists in firstarranginga plurality of blocks of insulating material end to end; applying a perforated plate to the sides of said blocks sticking pins through said plate and "partially into said blocks;

partially withdrawing said plateover said pins; applying other blocks to the ends of said pins; and then forcing said sets of blocks together. i

sulation-which consists in first arranging and cementing together a plurality of-blocks of insulating material end'to end; applying and cementing a perforated plate to the sides of said blocks; sticking pins through said plate and partially-into said blocks -;partially withdrawing said plate over said pins; applying cemented blocks to the other ends of said pins; and then forcing said sets of blocks together.
